Timing Gear Drive
Dohhhhh! there was speck of pizza on my monitor, didn't see the s in scat. :sign6:
Just a guess, but when the balancer gets torqued it maybe presses the gear into the crank and while not a wear pattern from movement might still make a slight groove or indent just from the clamping force. Who'd a thought that could be so deadly?
Still can't find the FAQ page, but then I'm web challenged.
